have you debug and check whether it hit the event chkIsOmani_CheckedChanged?

Probably what happening is that you hit server side but because of re-initialization of the data you lost your binding so no CheckedChanged event...

Hi,

You can use rowcommand instead of current coding.

Give CommandName to Chechbox in gridview. say "Check1"

You have to do the code on RowCommand event of gridview. check following example

C#

void ProductsGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
 {
   // CommandName property to determine which button was clicked.
   if(e.CommandName=="check1")
   {
     // code on checkbox select
   }
}

Thanks,
Bh@gyesh
